he topography of the ocean floor is as varied as dry land, and different kinds of fish gravitate toward different areas. In the waters off of southeastern Alaska, halibut can be found in hard, rocky areas that are flat and smooth. Rockfish, which are subject to overfishing, tend to be near rock piles that support cold-water corals and sponges and in areas with sharp peaks.
Members of the Alaska Longline Fishermen’s Association outfitted their boats with equipment that collects detailed information about the bottom of the ocean. Putting that data together, the nonprofit, in the town of Sitka, was able to create detailed maps of the ocean floor. The fishermen can then use the maps to be more efficient as they fish for halibut and black cod — and significantly reduce the number of rockfish they harvest inadvertently.
